Viscoelastomeric Connections in Seismic Structures
Nonlinear Kelvin and Maxwell impedances connect lumped masses to form arbitrary networks. Viscoelastomer-steel composite moment connections are modeled similarly, using auxiliary masses,...

Frictional Base Isolation Using a Layered Soil-Synthetic Liner System
The application of smooth geotextile liner materials to seismic base isolation of shallow foundations has been evaluated using laboratory testing and numerical analysis. Laboratory testing...

Recycling Bituminous Runway Pavement into Aggregate Base Course
The paper discusses the development of recycling existing bituminous runway pavement by pulverizing into aggregate base course. To best explain the design, construction procedures and...

This proceedings, World Marina '91, consists of papers presented at the First International Conference held in Long Beach, California,...

On Aseismic Hybrid Control System
One type of hybrid control system is proposed for protecting tall buildings subjected to strong earthquakes. The hybrid system consists of a base isolation system connected to either a...

Response of Sliding Base-Isolated Structures
Experimental and anlaytical results on the behavior of sliding isolated structures are presented. A mathematical model of friction of Teflon bearings is developed, calibrated, and verified....

Earthquake Energy Partitioning in Base Isolated and Dynamically Damped Structures
New earthquake energy spectra are proposed for practical design procedures using energy concepts. The spectra show integrated earthquake input energy of a unit mass with given natural...

A Study of Seismic Reliability of Base Isolated Building Comparing with Non Base Isolated Building
An approach to discuss the difference between reliability of base-isolated buildings and that of non base-isolated buildings is presented. The fragility analysis method in PRA procedure...

Response Variability of Isolated Structure Due to Randomness of Isolation Devices
Effect of randomness of restoring characteristics of an isolation device, which is considered to result from the randomness of material properties, configuration and setting error, on...

Conceptual Design for a Lunar-Base CELSS
Future human exploration is key to the United States National Space Policy goal of maintaining a world leadership position in space. In the past, spacecraft life support systems have used...

Planning the Developmemt of the OASIS Advisory System
This paper describes the evolution of the Operations Advisory and Simulated Intelligence System (OASIS). In its first phase, already concluded, a prototype was developed for testing the...

Fuzzy Sets in Civil Engineering?A Tutorial
This tutorial is an introduction to the theory of fuzzy sets and its applications in Civil Engineering, including its use within the framework of knowledge-based systems. The techniques...

Conflict Resolution, Reallocation and Management of Lake Texoma Resources
From its inception, Lake Texoma has created conflicts among users of its natural resources, including hydropower, water supply, flood control, and recreational users. Many attempts have...

An Expert System for the Motivation of Traffic Signals
A case study is presented describing the initiation and development of a prototype knowledge-based system for the motivation of traffic signal control, to be applied within a user-sensitive...

Structural Reliability Through Machine Learning From Case Histories
The development of a management tool for the control of structural safety is described. Artificial intelligence techniques of 'machine learning' are employed...

Management Strategies for Baseflow Augmentation
Management strategies for baseflow augmentation fall into the following categories: (1) range management, (2) upland vegetation management, (3) riparian vegetation management, (4) upland...

Water Quality Criteria for Cyanide in the Similkameen River, British Columbia
The toxicological and environmental significance of the major cyanide compounds is discussed. Data from earlier bioassays studies of cyanide are summarised and the ranges of median lethal...
